The XZ attack and timeline
29. October 2021 At this point Jia Tan pops up, and the first thing we see from him is an innocuous patch to the xz repository, and while a lot of people believe he started out trying his luck with another library also known as libarchive, this is not the case, I would bet it’s more of a backup looking at the dates, being that there are a few days in between as shown in this commit.
- Zip entry size unset now honors user requested compression level
- Suspicious libarchive pull request

Backdoor in upstream xz/liblzma leading to SSH server compromise
Potentially malicious commit by same author on libarchive: https://github.com/libarchive/libarchive/pull/1609
- WinRAR musste shady werden.

Making Amiga IFF Thumbnails Work in Linux
Full agreement, and with the addition of xpk¹/xfd² as natural extensions to that extensibility too. I see things like xfd supporting xz¹, and I'm simultaneously amazed that it exists and happy that I don't need to do xz {,de}compression on 68k ;)
I guess we have something similar-ish with libarchive⁴, but nobody(including me) has pushed the extra mile to get file dialogs to support random compression and decompression formats.
Beyond OT: I didn't realise how much stuff was still going on at aminet, but I love love LOVE that people are still dropping new car sets for Geoff Crammond's F1GP.

WinRAR zero-day exploited since April to hack trading accounts
I don't have a preview channel install handy to check, but apparently they're using libarchive so here's the full list assuming they expose everything it supports:

Windows 11 getting native support for 7-Zip, RAR, and GZ archives
Seems what they're using is BSD-liscensed: https://github.com/libarchive/libarchive/wiki

Ubuntu 23.04 (Lunar Lobster)
nearly every main distro I am aware of has both available. The reason you still see p7zip is because the CLI incompatibilities vs the newer 7z/7zip executables and the general licensing issues. Most users of "old p7zip" are actually using the actively maintained https://github.com/p7zip-project/p7zip which is updated, supporting unix permissions and zstd and so on.

7-zip 22.00 – APFS, Posix TAR, high precision timestamps
Thank you for pointing this out! This is the source of much confusion. Although Arch for example uses https://github.com/jinfeihan57/p7zip which seems to be reasonably maintained?
- Ark and 7-zip
-
Replace p7zip with upstream 7-Zip
Then you can compile p7zip from source: $ mkdir p7zip-git $ cd p7zip-git $ git clone https://github.com/jinfeihan57/p7zip .
- Don't Use RAR
- TIL there's a fork of the unmaintained p7zip port of 7-Zip
- I can't compress in 7zip with Ark and p7zip

will arch replace p7zip with normal 7-zip?
April 4th was the latest release. Had some commits in May. I think it is active.

Why is 7z so outdated?
I think the point is, the '7z' at 17.04 available in Arch Linux's repo is actually p7zip, the development of which is independent of 7-zip. So comparison of the version number is meaningless (if I am right). Also, p7zip 17.04 is released in April this year, not 2017, according to its release page
